Does ri know about all ruby classes?
문제
When I pass CSV
to ri
I get this output
Nothing known about CSV
I thought all ruby classes are documented with ri.
해결책
CSV is a part of standard library and is fully documented. That issue may be linked wit rvm using. Try to prepare rvm docs generate
command.
다른 팁
If RI returns "NOTHING KNOWN ABOUT..." the documentation may be missing.
RI documentation isn't included when Ruby is installed. It must be manually generated - ideally, immediately after installing EACH VERSION of Ruby (before the downloaded installation files are cleaned up).
To generate it:
$ rvm docs generate
If that doesn't work, check this RVM.io page for command options & scenarios.
